Minneapolis HVAC Air Filter Change Service Available to help. 952-469-3024

Breathing easy begins with clean air filters, which is why it’s incredibly important to replace them regularly in your home or office. Air filters exist to remove debris from the air before it enters your HVAC system. Clean filters trap harmful bacteria and pollutants, combating illness and allergies. In addition, clean filters save you money – according to the EPA, regularly changing your filters can cut five to 10 percent off your bill on average! When the filter is clean, debris will be trapped by the filter and not by the system itself, promoting HVAC efficiency.

The best time to replace your filter will generally be determined by your filter type. Refer to your HVAC manual and jot down your filter’s size and style – it will be helpful to have that information on hand while shopping! A good rule of thumb is to check your filters once a month. A typical suburban home without pets should plan to replace every three months. If you have a furry friend or two, you should replace every two months. Write the date on your filter before you install it so you’ll easily remember when you last replaced.

Keep the dirt in the super collector vacuum and not your vents.

While duct cleaning alone doesn’t seem that necessary, there are cases where cleaning the HVAC unit and ductwork could be useful.  A cleaning every 5-7 years by a company that doesn’t make the duct cleaning a waste of money can provide relief from a whole host of problems. … Additionally, if there is suspected mold spores or growth in the ductwork, a thorough cleaning will remove the mold and keep it from spreading into the rest of the home.



Rule number 1—Meet the people you help.

7 Common Reasons Why Your Air Conditioner Is Not Cooling Properly

1. Dirty cooling coils. Your air conditioner has a set of indoor coils that absorb heat from your workplace air, as well as a set of outdoor coils that transfer heat from your workplace to the outdoors. If either of these coils have a layer of dirt on them it becomes much more difficult for heat to transfer between the coils and the air that’s blown over them. This can greatly reduce your system’s ability to remove heat from your workplace and the air that comes out of your vents will be warmer than it should be.

2. Refrigerant leak. Refrigerant is what flows through your air conditioner coils and actually moves the heat from inside your workplace to the outside condenser unit. If your system has a refrigerant leak it will not be able to adequately move heat out of your workplace. Your air conditioner will run, but will not provide optimal comfort.

3. Blocked condenser unit. Condenser units are located outside, where they can be blocked by all kinds of unsuspected problematic things. If your condenser unit is obstructed, it will not be able to adequately release heat from the condenser coils. This means that the heat that is removed from your system will not be released properly.

4. Dirty air filter. When your air filter is dirty, the amount of air that is able to blow over your evaporator coils is restricted. When this happens, much of the warm air that your air conditioner pulls from your workplace’s air will not actually be cooled.

5. Compressor problems. Your air conditioner’s compressor is responsible for making sure the refrigerant is at optimal pressure, making it one of the most important parts of your unit. Without it, your system would not be able to absorb heat from the rooms in your workplace and transfer it outside. If it starts to malfunction, your air conditioner has no chance of cooling your workplace properly.

6. Old system. When an air conditioner reaches the end of its operating life it will not be able to cool your workplace like it used to. This is just a natural fact of an air conditioner’s lifespan, which is why it’s important to replace your system when it is no longer able to perform effectively.

7. Improper thermostat settings. If your thermostat’s fan setting is set to “on” your air handler will blow air even when your system isn’t in a cooling cycle. As a result, some of the air that comes out of your vents will feel warm. You can adjust this by switching the fan setting to “auto” instead. Another setting to check is whether your system is in “heat” or “cool” mode. Your air conditioner will only be turned on if your thermostat is set to “cool.”
